The gas phase reaction `2NO_(2)(g) rarr N_(2)O_(4)(g)` is an exothermic reaction. The decomposition of `N_(2)O_(4)` in equilibrium mixture of `NO_(2)(g) and N_(2)O_(4)` can be increased by :

Options

A. lowering the temperature
B. increasing the pressure
C. addition of an inert gas at constant volume
D. addition of an inert gas at constant pressure

Explanation

To solve the question regarding the gas phase reaction \(2NO_2(g) \rightleftharpoons N_2O_4(g)\), we need to analyze how different changes affect the equilibrium position of the reaction. The reaction is exothermic, meaning it releases heat when moving from \(NO_2\) to \(N_2O_4\).

### Step-by-Step Solution:

1. **Understanding the Reaction**:
The equilibrium reaction is:
\[
N_2O_4(g) \rightleftharpoons 2NO_2(g)
